Description

When you notice coolant puddles under your TEF20 or see steam coming from around the thermostat area, you know that housing has finally given up after decades of thermal cycling. This replacement thermostat housing gets your diesel TEF20 back to proper temperature control, stopping those leaks and ensuring your cooling system can do its job when you’re working hard.

What You’re Getting

Heavy-duty casting designed specifically for TEF20 diesel engine mounting
Proper coolant passages that maintain correct flow for temperature regulation
Durable construction that resists the cracking and corrosion that killed your original
Direct replacement with correct hose connections – no modifications needed
Secure thermostat mounting that ensures proper sealing and operation

Built for Real Farm Work

Your Ferguson TEF20 diesel has been a farm workhorse for generations, handling everything from cultivating and mowing to running PTO equipment. The thermostat housing takes constant thermal cycling – cold starts to operating temperature thousands of times over the years, and eventually the original casting develops stress cracks or internal corrosion that disrupts coolant flow.

Made to Last

This replacement matches original specifications for proper coolant flow dynamics. The robust casting resists the cracks that develop in aged housings, giving you reliable service for years to come. It’s built to handle the temperature swings and vibration that come with real farm work.

Installation Notes

This housing is designed exclusively for diesel TEF20 models – petrol engines use different configurations. Clean all mating surfaces thoroughly before installation. Use new gaskets and proper sealant where specified. While you’re in there, it’s smart to replace the thermostat and gasket too – they’re cheap insurance and everything’s already apart.
